VS2012开发ActiveX插件尝试1

今天闲来无聊研究了下 ActiveX插件开发,以前一直以为很牛逼,然后发现还是比较简单的东西..

首先: 在开始前准备好 VS12开发工具,cabarc.exe 工具(注:这是用来将文件打包成cab的工具,cab包ie浏览器才会安装它,提供下载见文章最后)

开始:

1.新建一个Windows窗体控件库

2.新建用户控件

3.添加一个接口名为:IObjectSafety(此名固定用法)

添加的代码:(代码请勿改动)

 1 using System;
 2 using System.Runtime.InteropServices;
 3 
 4 namespace MyFirstActiveX
 5 {
 6     [ComImport, GuidAttribute("CB5BDC81-93C1-11CF-8F20-00805F2CD064")]
 7     [InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIUnknown)]
 8     public interface IObjectSafety
 9     {
10         [PreserveSig]
11         int GetInterfaceSafetyOptions(ref Guid riid, [MarshalAs(UnmanagedType.U4)] ref int pdwSupportedOptions, [MarshalAs(UnmanagedType.U4)] ref int pdwEnabledOptions);
12 
13         [PreserveSig()]
14         int SetInterfaceSafetyOptions(ref Guid riid, [MarshalAs(UnmanagedType.U4)] int dwOptionSetMask, [MarshalAs(UnmanagedType.U4)] int dwEnabledOptions);
15     }
16 }

4.是用户控件(这里是UserControl1) 实现这个接口

5.用户控件添加特性 Guid guid为自己手动生成...(在vs工具->创建GUID)

6.给用户控件添加代码 ps:实现IObjectSafety的代码(此段代码固定)

7.修改生成属性,项目->右键->属性请看下图演示.修改一下2处

8.ok 以上都是模板话的工作..... 现在开始是代码工作..... 在用户空间中拖一个button

然后双击写一个处理方法为: MessageBox.Show(DateTime.Now.ToString("F"));

9.ok,生成一下,找到 bin目录下的 dll文件(后面马上用到) ,就此控件代码任务完成.下面开始测试部分

10.新建一个asp.net网站(MVC什么都行), 将刚刚的dll 扔到网站根目录下或者文件夹下我这使用了一个名为DLL的文件夹

在页面上添加代码:

1  <object id="mytt" classid="clsid:195FE621-2DCA-43DC-BF54-A13E16EFC58E"  
2        codebase="/DLL/MyFirstActiveX.dll"></object>

View Code

注:这里的guid是我控件里自己生成的guid不是 IObjectSafety 接口中的guid

11.调试项目:点击测试按钮得到结果如图:

12.上面是按钮触发效果...这里也可以使用js 调用 c#代码:

如下代码:

1  <script type="text/javascript">
2         $(function() {
3             var s = $('#mytt')[0];
4             s.test();
5         });
6  </script>

我是用了jquery需要的自引用

最后感谢蜗牛的大力支持

ok,就说到这好困我去睡觉去了...大家晚安 2013年9月29日23:55:22

最后附上代码下载: 网站源码自己搞吧..不上传了,直传插件部分源码下载
